I've been riding for 4 months with padded mt bike shorts,but am looking into road bike shorts to get a little faster. They're a couple of Strava segments that I have to beat my brother at,lol... My problem with finding the right shorts is, I'm tall, skinny, with pretty long legs. 6'4" 165 pounds to be exact, if I buy a large/xl most shorts will be to loose. If I get a medium, they will be very short(many in that size are 9" long). Any suggestions?
